[Freeswitch-users] freeswitch CPU usage

[Giovanni Maruzzelli]

Vlasis,

please calm down and try to understand the context you're interacting with.

This is not a matter of civil rights or politically correctness or
different sensibilities or respect for the freedom of speech or
whatever thing of this kind.

This is a matter about a consistent, practical and every time asserted
displease from the core team developers (and most of the not-so-core
team developers) toward stress tests and performance measurements.

It has been stated many many times, and the reason is: because fake
test (sipp) does not gives you results that reflects in real world
case, because sipp is black magic, because there are many variable
involved (OS, hardware, kind of load, etc), because this is likely to
attract undue interest on naked figures [we can do 1 million
cps!!!!!], because to get it right involves a tremendous lot of
experience, because the only useful test for your usage is to put in
production a reasonable dimensioned machine and then see of it goes,
because we read all the message in the list and particularly on
performance themes we are pushed to intervene before too many wrong
things are asserted, we don't like threads debating about performance
testing.

But, because we're human and nice, and helpful and caring, on the side
of the bashing we also offer pearls of wisdom that can be used for the
purpose, instead of simply bashing or ignore the poster.

So, take it as a mysterious ways of the Zen Masters to visit black art
on performance test posters.
